Not many applications when you are more than 20 seconds WOT.

Hypothetically, if you wanted to wanted to go all out to avoid heating of fuel would it be possible to run return to main tank and have a big arse lift pump

 

or plain not practical?

Defeats the purpose of a surge.

The DW440 can be staged to run at 65% at low load and triggered to run 100% full load. Then there's the option of boosting voltage. I'm not sure if an off the shelf surge tank will fit my SZ Territory otherwise I'd retain the intank 460 and go Plazmaman external with twin staged Pierburg pumps.

@Romulus apologies for hijacking thread

Weren't you M6 something something before?

I had twin 044s on a plaz surge and have got 2 pierburgs to replace them so will be more or less same as yours, haven't opened up the fuel tank to check lift pump but would be surprised if it wasn't a 460

 

Q about return line was conjecture only, obviously the standard pot has its scavenging limits and in that scenario the surge would basically be a buffer albeit an expensive one

 

I wanted to use a hobbs switch so the 2nd pierburg only came on at ~5psi boost, pretty sure this has been done before

I used a hobbs pressure switch to activate the 2nd Pierburg external pump. IIRC is was set to come on over 11psi. My G6ET made 511rwkw on E85 using this setup.
